SPECIFICATION forming part of Letters Patent No. 745,935, dated December 1, 1903;.

Application filed June 19. 1903. Serial No. 162,249. (No model.)

To all whmn it may concern:

Be it known that I, ARTHUR BAILY VANCE, ofPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Line- Marking-Type Attachments for Type-Writing Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in typewriting machines, and is a simple device for facilitating the making of lines, particularly dotted lines, in machines employing inking-ribbons, without the necessity of having to repeatedly strike akey, as has been heretofore necessary in tabulating or making statements of accounts. The device is especially designed for use on a type-bar typewriting machine, such as the Remington, but is not restricted to such a machine.

The invention, in brief, comprises a rotatable liner wheel or disk provided with needle-points and adapted to be held firmly against the ribbon and paper by the depres sion and holding down of a key, and while so held the carriage is released by depressing a release or paragraphing key, as now customarily employed, and as the carriage moves to the left the wheel is caused to rotate by the needle-points biting the paper, and thus forcibly turning the wheel so that it produces a series of dots on the paper from the interposed ribbon.

The accompanying drawings illustrate two forms of such a device and the manner of using the same on a type-bar machine; but I do not restrict myself to the precise construction shown, referring to the claims for summaries of the essential features of the invention. The device, moreover, is adapted to be used as an ordinary punctuation-type for example, as the period-typeand it can be used on double-type-carrying-bar machines, such as the Remington, or on singletype-carrying-bar machines, such as the Caligraph.

In the accompanying drawings, Figure 1 is a detail sectional view of part of a type-writing machine, showing a platen, paper, inkribbon, and type-bar carrying my lining device and uplifted in position to bring the liner in operative position. Fig. 2 is a magnified view of the lining device detached from the bar. Fig. 3 is aside view of Fig. 2. Figs.

4 and 5 are magnified front and side views of a modified form of the liner-wheel.

As shown in Figs. 1 to 3, the liner comprises a disk or wheel a, rotatably journaled on a stub-shaft b, projecting from the side of a body 0, which body is provided with a shank 61, adapted to be engaged with and secured to the end of a type-bar B, of ordinary construction or such as is used in any of the well-known type-bar machines. In the example shown the bar is one of the Reming' ton machines. Hence the body 0 is a typebody and is provided with an upper-casetype character on its upper end, while the wheel a occupies the relative position thereto of the period-type, as in the present instance the wheel is a dotting-wheel, and when not used as a liner will serve as the periodtype. This wheel a has a number of radial teeth a, each terminating in a blunt point about equal in surface area to the ordinary period-type; but from the center of each tooth a projects a fine needle-point a just long enough to pass through the ribbon R and engage the paper P without damaging the ribbon or puncturing the paper in an unsightly manner. Attached to the shank d below the wheel is a spring-plate f, that extends under shaft 1) and is provided with a notchf' to permit the wheela to rotate thereby. The tongue f on the end of the spring lies against the end of the wheel, and in connection with the part f at the rear side of the wheels keeps the wheel in the desired position on the shaft 1). The adjacent tongue on the spring bears against one of the facets of the wheel and will ordinarily keep the wheel in such position that one of its teeth a will be in position to serve as a period-type when the type-bar is properly actuated, but will not prevent the rotation of the wheel. In Figs. 4 and 5 the wheel is of simpler construction than in Fig. 1, being simply peripherally notched or serrated and having on the apex of each tooth e a period-point e, from which spring the central needle-points (1 This wheel is mounted upon the type-body 0, just as wheel a in Figs. 2 and 3, and operates like the latter, and is provided with a springf,

which will normally keep some one of the 5 points 6' in position to act as a period-type when not used as a liner.

The operation is simple. The liner-wheel a h or its equivalent is attached to one of the type-bars of the machine. It may be mounted on an individual-type body or mounted on a double-type body. type body of the machine to be used in place of the period-type, which can be dispensed with where such a Wheel is employed. VVhenever the operator desires to use the device for liningas, for instance, in tabulating accountshe depresses the key controlling the chine,and adapted to operate as a type characbar carrying the wheel and holds it down, thereby pressing the wheel against the ribbon, its points a passing through the ribbon and sticking into the paper. Then by releasing the carriage the latter moves to the left, and as the points a engage the paper the wheel is forced to turn thereby, and at each needle-point puncture a dot is made by the blunt tooth pressing the ribbon against the paper, thus producing a line of dots very rapidly and with but two movements of the opcrators handsto wit, first, depression of the liner-key; second, depression of the carriagerelease or paragraphing key. Obviously the construction and mounting of the liner-key and its support and attachment to the keybar can be considerably varied within the scope of my invention, and must and will be varied to suit the particular machine to which the attachment is applied.

While I have described the liner-wheel as forming a dotted line, it might form a line of other character-or design, continuous or broken, by properlyshaping its configuration.

As above stated, the invention is especially designed for use on machines employing inking-ribbons, and is not intended to be used as a printing-wheel, which receives ink from a supply and transfers it to the paper. Further,while I have described the wheel as used for making lines by the longitudinal motion of the carriage, it is obvious that if the wheel be turned to a position parallel with the axis of the platen it can be used to rule the latter with vertical lines by simply rotating the platen while the liner-key is depressed.

An important feature of the invention is the needle-points, whereby the wheel is rotated by being pressed upward into engagement with the paperou the moving platen whilein contact with the ribbon and binding the latter against the paper. Another important feature is making a liner attachment which can be attached to a type-bar and operated like an ordinary type. Another feature is making a liner of this nature which when not used as a liner can be used as an ordinary type character.

Having thus described my invention, what I show it on the periodpenetrate the ribbon and engage the paper,
